It applies on top of 17.11 + [1] and [2]. Some parts of dpdk use their own management threads. Most of the time, the affinity of the thread is not properly set: it should not be scheduled on the dataplane cores, because interrupting them can cause packet losses. This patchset introduces a new wrapper for thread creation that does the job automatically, avoiding code duplication.
